Answer:

Number of yellow marbles = 6

Number of purple marbles  =  24

Step-by-step explanation:

Number of yellow marbles = x

Number of purple marbles  = 3x + 6

Total marbles = 30

x + 3x+6 = 30

4x + 6 = 30

      4x = 30 - 6

      4x = 24

        x = 24/4

      x = 6

Number of yellow marbles = 6

Number of purple marbles  = 3 * 6 + 6 = 18 + 6 = 24
